Question

Find A to the nearest degree. A ≈ ____ degrees.

Answer 1

to find A

 arc cos(267/391) = 46.93

 to the nearest degree = 47 degrees

Answer 2

Answer:

47°

Step-by-step explanation:

We are given a right angles triangle having the base length = 267 unit and hypotenuse = 391 unit.

Now, using the trigonometric forms of angles in a right triangle.

We have, $\cos A=\frac{adjacent}{hypotenuse}$

i.e. $\cos A=\frac{267}{391}$

i.e. $\cos A=0.683$

i.e. $A=\arccos 0.683$

i.e. A = 46.92°

Hence, the value of A to the nearest degree is 47°
